A Rover on the Red Planet! Spirit Will Look at the Geology of MarsNews story originally written on January 14, 2004

NASA’s rover, named Spirit, has successfully landed and will soon be scouting the surface of Mars for interesting geology!

Scientists are interested to know whether the depression where Spirit landed was once a lake. Currently, there does not appear to be liquid water at the surface of Mars, but this may not have always been the case. It is possible that large amounts of liquid water were once at the surface. If water was available, living things may have been present as well.

Spirit is looking at the nearby sedimentary rocks for clues to understand what the environment was like in the past. These types of clues are not just important for understanding Mars. Information from sedimentary rocks is also used to understand what past environments were like on Earth.
